This introduction to the potential of media is directed to three audiences: teachers, churchmen, and youth-serving agencies. So that each of these audiences reads the sections relevant for them, the book is organized like a programed text, using a branching system. The point of the book is that film and television, when they are creative and open-ended, and followed by stimulating discussion, can be one of the most exciting and effective means of discovery and communication available to us today.
